High Flow Heads On Stock Motor

[a91what]

Just put on the heads then add
1.7rr
Long runner intake, gt40 or better
Long tube headers and x pipe
65mm tb
75mm maf or larger
24lb injectors

With the stock cam I bet on 280+rwhp

Any decent blower on top of that plus a maybe a spring upgrade would take you to the block limits. If the crank is forged... bonus.

Always upgrade valvesprings IMO.

If we're trying to get to the blocks limit don't you think the cylinder heads are an even bigger waste of money with a blower?

It just depends on how hard we want to push the bower.

So after reading through the replies you all have given and why i would build a 408 intread of the 302. Well the friend i got these heads from also gave me the rest of the 408 minus block (which had cracked) and a few other parts that ill need. so i have the cam, intake, heads, rotating assembly and what not. I figured I might as well use the heads while saving for the block.

Thats a good plan, it will be slugish if you don't add the supporting cast. I would run what you got in the car and build a block up with the 408 stuff and drop it in, this way you can take care of those unexpected things and save on gaskets.

Just save for the block and use the heads on the 408. No reason to spend on 302 parts to make it work.

 

[silent mumbler]

Yeah thats the plan Im going with. Ill have to settle on some Fauxmasters from oriellies for my "performance upgrade" until the motor is done.

Despite the pros and cons, those heads will def be more at home on a larger cube motor.
